COMBINED POCKET-CASE AND STERIIiIZEIt FOR SURGICAL INS'IRUIVIENTLS.

Specification of Letters Patent.

Patented Aug. 10, 1920.

Application fi-lea December 21 1918. Serial No. 267,765.

To all whom it may concern:

Be it known that I, Aueus'ro H. or. GonNAcA a citizen of the United States, residing at Gobleville, county of Van Buren, State of Michigan, have invented certaln new and useful Improvements in Combined Pocket-Cases and Sterilizers for Surgical Instruments, of which the following 1s a specification.

This invention relates to improvements in combined pocket cases and sterilizers for surgical instruments.

The main object of my invention 1s to provide a combined pocket case and sterilizer for carrying thermometers, hypodermic syringes and other small surgical instruments, which is compact and of convenlent form for carrying in the pocket, and also one which is easily charged with the sterilizing material.

A further object of my invention is to so construct said case that the sterilizing material may be centrally located with respect to a plurality of perforated containers for such surgical instruments, and to provldc means whereby the perforations of said containers may always be arranged in fixed posltlons relative to said sterilizing material so as to conduct the full effect thereof to said instruments.

A still further object of my invention is to form said case in an exceedingly simple and economical manner, and so that it will be practical and efficient in use.

These and other objects of my invention are set forth in the following specification, and shown in the accompanying drawing, which forms a material part of this disclosure, the features of novelty which constitute my invention being pointed out in the claims annexed hereto.

In the drawings Figure 1 is a side View of a structure embodying the features of my invention.

Fig. 2 is a top view partly broken away of the structure shown in Fig. 1.

Fig. 3 is a vertical section on a line corresponding to line 33 of Fig. 2.

Fig. 4 is a vertical section on a line corresponding to line 4-4 of Figs. 1 and 3.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

In carrying my invention into practice I form an outer casing 1 of metal, or other suitable material, which may be of any size or shape, although I prefer to flatten the same in cross section as shown in the drawings, so that it may be conveniently carried in a pocket, and whichmay be constructed in any usual or desired manner.

In the top of the said casing is formed a threaded central neck 2 for the closure cap 3, a gasket being arranged in the top of said. cap to form a tight joint with the top of said neck. I also form openings 5 in the top of said casing which are disposed at each side of the neck 2, which receive the ends of tubular sleeves or bushings 6, which are provided with lateral longitudinal grooves 7 in their sides adjacent to the neck 2.

Tubular containers 8, adapted to contain small surgical instruments, are arranged within the bushings 6, and are provided with tongues 9 adapted for en agement with the grooves 7 so as to hold the said containers in fixed relation to said bushings and prevent them from rotary movement therein. The containers have perforations 10 in their inner walls facing the interior of the casing and forming open communications between the interiors of said casing and containers.

The tops of the containers are adapted to be closed by screw-threaded caps 11, and by gaskets 12 interposed between said caps and the containers. Screw-threaded caps 13 are arranged to close the tops of the bushings 6.

Secured centrally to the interior of the cap 3, and projecting inwardly into the neck 2, is a boss 14, adapted to receive and hold a rod 15, which carries a roll of absorbent material 16, which may be formed of wicking or other desired material. This rod may be provided with a cross-head 15 at its lower end having a recess 15 which may engage a head or projection 20 formed on the bottom of the casing, so as to hold said rod against displacement.

In practice the roll of absorbent material is dipped into, or impregnated with, a suitable sterilizing medium, such for example as formaldehyde, and placed in the casing, the cap 3 being then screwed tightly onto the neck 2 to seal the casing. .The fumes from the evaporation of the disinfectant fill the casing, and pass through the perforations 10 into the containers 8, enveloping and acting upon the instruments therein contained. The absorbent material may be charged with the'sterilizing medium as often as necessary or desirable, and the material itself may be changed when required. The caps 11 hold the'containers' and their contents securely within thercasing 1, while the tongues 9 in the grooves 7 prevent the containers from turning, so that the open ings 10 will always be properly presented for the action of the sterilizer,

' The bushings 6 and the neck 2 may be soldered, brazed or otherwise securedin place in the topof the casing.

My case and sterilizer is simple in construction, economical in manufacture, and

is eificient and convenient in use. 7 v

, 'What I claim as new anddesire to secure by Letters Patent is 1. A pocket case and sterilizer comprising acasing having a sterilizing element disposed therein, bushings mounted in and projecting abovethe top of said casing, perforated containers inserted into the casing through said bushings and in open communication with the interior of said casing, tongue and groove connections between said bushings and containers, and caps upon said bushings, said caps engaging. the tops of said containers to hold them fixed in place.

2. A pocket case and sterilizer comprising a casing having a sterilizing element therein, bushings mounted; in; and projecting above the top of said casing, perforated containers inserted into the casing through said bushings and resting on the bottom'of said casing, the upper ends of said'containers projecting above the tops of said bushings, tongue and groove connections between the said containers and bushings, and caps screwed upon the said bushings and engaging the tops of said containers to hold them fixed in place. 7

In testimony whereof, I have signed-my name to this specification, this 6th day of December, 1918. V v I AUGUSTO H. DE GOENAGA.
